INA110KUG4 Equivalent & Substitute Parts

Part Overview

The INA110KUG4 is a single-channel instrumentation amplifier manufactured by Texas Instruments in a 16-SOIC surface mount package. This device is classified as a linear amplifier and is designed for precision signal conditioning applications requiring low input bias current and low input offset voltage.

The INA110KUG4 has been discontinued at DiGi Electronics. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for systems utilizing this instrumentation amplifier.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the INA110KUG4 is determined by strict equivalence across the following critical parameters:

Electrical Specifications:

• Amplifier type (Instrumentation)
• Number of circuits (1)
• Slew rate (17 V/µs)
• -3dB bandwidth (2.5 MHz)
• Input bias current (20 pA)
• Input offset voltage (200 µV)
• Supply current (3 mA)
• Output current per channel (25 mA)
• Supply voltage range (12 V to 36 V)

Physical and Environmental Specifications:

• Mounting type (Surface Mount)
• Package type (16-SOIC)
• Operating temperature range (0°C to 70°C)
• Moisture sensitivity level (MSL 3)

Compliance and Regulatory:

• RoHS3 compliance
• REACH status (Unaffected)

Substitute parts must match all electrical parameters, package specifications, and environmental ratings. The INA110KU is identified as the manufacturer-recommended substitute based on identical electrical and physical specifications.

Parameter Comparison

Engineering Selection Recommendations

The INA110KU is the direct equivalent substitute for the discontinued INA110KUG4. Both parts are manufactured by Texas Instruments and share identical electrical specifications, package configuration, and environmental ratings.

Substitution Basis:

The INA110KU maintains full electrical and mechanical compatibility with the INA110KUG4. All critical parameters—including slew rate, bandwidth, input bias current, input offset voltage, supply current, output current capability, and supply voltage range—are identical. Both devices are housed in the 16-SOIC package and operate across the same temperature range (0°C to 70°C).

Compliance Status:

Both the INA110KUG4 and INA110KU are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components. Moisture sensitivity level (MSL 3) is identical for both parts.

Availability Consideration:

The INA110KU is currently in active production status with documented inventory availability (1,577 pieces in stock), whereas the INA110KUG4 is discontinued. The primary difference between these parts is the packaging format: the INA110KUG4 was supplied in a standard package format, while the INA110KU is supplied in tube packaging. This packaging difference does not affect electrical performance or mechanical compatibility in surface mount applications.
